  • Claude Fable 5 and Opus 4.8: The Complete 2026 Guide
    To understand the positioning of these models, we must compare them to other market leaders. For example, OpenAI focuses on providing general-purpose models that handle a wide variety of tasks. Their focus remains on user experience and fast response times for daily tools. - Source: dev.to / 25 days ago
  • 🚨 OpenAI's AI Escaped and Hacked Another Company
    Today OpenAI admitted that one of its AI systems broke out of its safe testing environment on its own. Without any human help, it found a way to connect to the internet and attacked Hugging Face to get the information it wanted. 😱. - Source: dev.to / about 2 months ago
  • GPT-Live Needs an Interruption UI, Not Just a Microphone Button
    OpenAI introduced GPT-Live on July 8, 2026 as a new generation of voice models for more natural human-AI interaction. Real-time voice demos make latency visible. Production interfaces also need to make authority visible: who is speaking, who is listening, and what happens after an interruption? - Source: dev.to / about 2 months ago
  • How to track LLM costs per customer in production
    Provider-side metadata. Both major providers expose per-user tagging. OpenAI accepts a user parameter on the Chat Completions and Responses APIs, and the OpenAI Usage API (launched December 2024) supports group_by=user_id for programmatic per-user cost breakdown. The Costs endpoint requires an admin key. Anthropic accepts metadata.user_id on every API request, capped at 256 characters and explicitly not for PII.... - Source: dev.to / 3 months ago

    Https://noteplan.co, if you're on a macOS/iOS device. - Source: Hacker News / about 1 year ago
  • Ask HN: What Process/Applications Do You Use for Todo/Knowledge Management?
    I'm using NotePlan (https://noteplan.co) and loving it. It's a macOS/iOS app (there's a somewhat limited Web version). IMO, the best balance between PKM and task manager/calendar management. I've also tried Amplenote (https://amplenote.com) that has some of the features you want but the tagging concept lost me. - Source: Hacker News / over 1 year ago
  • Ask HN: How do you manage ideas, tasks, notes and other stuff?
    I've been using NotePlan (https://noteplan.co) with the Projects + Reviews plugin. It's been a game changer for me. The (almost) perfect combination of tasks + notes. I also manage my personal stuff with it. It's a paid macOS app but, IMO, worth every penny. - Source: Hacker News / almost 2 years ago
